The inventions change the world of Americans
Thanks to technology, our life today is very different from the previous century. Here are the American technologies that have changed people's lives.
Module Lunar lander

The United States was the first country to bring people to the Moon, so it was also the first country to own the Lunar lander. In 1969, exactly 50 years ago, Neil Armstrong became the first person to walk on an object outside of Earth.
When the spacecraft arrived at the Moon's orbit, a smaller module separated from the mother ship helped astronauts land safely on the surface of the object. New York engineer Thomas Kelley is the father of this creation, there is a team of 7,000 engineers and technicians working together behind his back.

Invented in 1947, Bell Laboratories created the world's first semiconductor device with the size of an iPod music player. Without resistors and semiconductor devices, today's electronic devices will not be created. So in a way, Bell Labs engineers can also be called the father of all technology devices.
Traffic lights
This is an American invention created in 1912.
Perhaps none of us like the feeling of waiting for a red light, but this is a valuable invention and contributes to changing the face of traffic around the world. This is an American invention created in 1912, helping to reduce traffic accidents as well as traffic congestion.
Microwave
Microwave is a device that is present in most kitchen corner households. But ironically, this is an invention not used for the kitchen from the beginning it was created.
In 1945, engineer Percy Spencer created a radar emitter for Raytheon, to help the radar become more sensitive across different wavelengths. Eventually he accidentally realized that the chocolate was deformed and melted when placed inside something that we would later call an oven.
Laser
The first laser beam was created by Theodore H. Maiman in 1960.
The most common laser beam in the public is at concerts or entertainment events. Imagine how boring these outdoor activities are without the appearance of colorful light rays.
The first laser was created by Theodore H. Maiman at Hughes Research Laboratory in Malibu, California in 1960. In addition to entertainment purposes, lasers are also used for other industries such as health and astronomy. mechanical engineer.
Email or Email
Clearly, email has replaced the way we exchange long-distance information and is the basic foundation for today's instant messaging services. This invention was created in 1971 by US Department of Defense programmer Ray Tomlinson to help agency employees have a tool to exchange messages through an affiliate network.

3D printing is an emerging trend and will also dominate long-term in most industries from engineering to manufacturing. Invented by Chuck Hull - founder of 3D Systems, this technology has, is and will completely change the way we live in the future.
Currently, 3D printing technology has been widely applied to create materials quickly and compactly in industries such as health, mechanics, parts of large vehicles, or even weapons. , home for astronauts on Mars, .
GPS
Created by the US Department of Defense in 1973 and civilized in 1993, anyone can use it. GPS is now an essential tool for military, defense, scientific research and domestic security activities. On the civil side, it is clear that a tool to help you determine your location is a very important and necessary invention.
